The Measure Phase is the second phase in the Six Sigma Define-Measure-Analyze-Improve-Control (DMAIC) methodology. In a previous post, we discussed the Define Phase in the Six Sigma DMAIC Methodology and all the elements in that Phase.

During the Measure phase, the focus shifts from “do we agree that X is a problem” to “what’s the phenomena that is happening such that it is a problem?” For example, if a machine is failing, it would be good to know how often, when it’s failing, and other items related to the defect. All of these questions in the Measure Phase is answered with Data. So, it’s no surprise then that in Measure we learn how to apply data analysis in a practical way that helps us to narrow down the problem.

In other words, collect data.

But, it’s not just data. It’s gut or hunch also.

Here’s what I mean: often times, we begin with “hunch” or “gut” and that gives us a good place to start of where to collect data. Ideally, we want to marry our gut hunch with data.

The Objectives of the Measure Phase

Here’s the Measure Phase Storyboard that sums up the following objective:

Through more detailed analysis, select a problem and problem space that will have the biggest impact on the organization and set an improvement target.
